|
|
|
**Note:** Always select the same GitHub tag as the released version you use to ensure you have the correct example configuration and documentation. The `main` branch might contain unreleased changes.
|
|
|
|
## Overview
|
|
|
|
Tailscale is [a modern VPN](https://tailscale.com/) built on top of [Wireguard](https://www.wireguard.com/). It [works like an overlay network](https://tailscale.com/blog/how-tailscale-works/) between the computers of your networks - using all kinds of [NAT traversal sorcery](https://tailscale.com/blog/how-nat-traversal-works/).
|
|
|
|
Everything in Tailscale is Open Source, except the GUI clients for proprietary OS (Windows and macOS/iOS), and the 'coordination/control server'.
|
|
|
|
The control server works as an exchange point of Wireguard public keys for the nodes in the Tailscale network. It also assigns the IP addresses of the clients, creates the boundaries between each user, enables sharing machines between users, and exposes the advertised routes of your nodes.
|
|
|
|
headscale implements this coordination server.
|
|
|
|
## Status
|
|
|
|
- [x] Base functionality (nodes can communicate with each other)
|
|
- [x] Node registration through the web flow
|
|
- [x] Network changes are relayed to the nodes
|
|
- [x] Namespaces support (~tailnets in Tailscale.com naming)
|
|
- [x] Routing (advertise & accept, including exit nodes)
|
|
- [x] Node registration via pre-auth keys (including reusable keys, and ephemeral node support)
|
|
- [x] JSON-formatted output
|
|
- [x] ACLs
|
|
- [x] Taildrop (File Sharing)
|
|
- [x] Support for alternative IP ranges in the tailnets (default Tailscale's 100.64.0.0/10)
|
|
- [x] DNS (passing DNS servers to nodes)
|
|
- [x] Single-Sign-On (via Open ID Connect)
|
|
- [x] Share nodes between namespaces
|
|
- [x] MagicDNS (see `docs/`)
|
|

|
|
## Roadmap 🤷
|
|
|
|
Suggestions/PRs welcomed!
|
|
|
|
## Running headscale
|
|
|
|
Please have a look at the documentation under [`docs/`](docs/).
|
|
|
|
## Disclaimer
|
|
|
|
1. We have nothing to do with Tailscale, or Tailscale Inc.
|
|
2. The purpose of writing this was to learn how Tailscale works.
|
|
|
|
## Contributing
|
|
|
|
To contribute to Headscale you would need the lastest version of [Go](https://golang.org) and [Buf](https://buf.build)(Protobuf generator).
|
|
|
|
### Code style
|
|
|
|
To ensure we have some consistency with a growing number of contributes, this project has adopted linting and style/formatting rules:
|
|
|
|
The **Go** code is linted with [`golangci-lint`](https://golangci-lint.run) and
|
|
formatted with [`golines`](https://github.com/segmentio/golines) (width 88) and
|
|
[`gofumpt`](https://github.com/mvdan/gofumpt).
|
|
Please configure your editor to run the tools while developing and make sure to
|
|
run `make lint` and `make fmt` before committing any code.
|
|
|
|
The **Proto** code is linted with [`buf`](https://docs.buf.build/lint/overview) and
|
|
formatted with [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html).
|
|
|
|
The **rest** (markdown, yaml, etc) is formatted with [`prettier`](https://prettier.io).
|
|
|
|
Check out the `.golangci.yaml` and `Makefile` to see the specific configuration.
|
|
|
|
### Install development tools
|
|
|
|
- Go
|
|
- Buf
|
|
- Protobuf tools:
|
|
|
|
```shell
|
|
make install-protobuf-plugins
|
|
```
|
|
|
|
### Testing and building
|
|
|
|
Some parts of the project requires the generation of Go code from Protobuf (if changes is made in `proto/`) and it must be (re-)generated with:
|
|
|
|
```shell
|
|
make generate
|
|
```
|
|
|
|
**Note**: Please check in changes from `gen/` in a separate commit to make it easier to review.
|
|
|
|
To run the tests:
|
|
|
|
```shell
|
|
make test
|
|
```
|
|
|
|
To build the program:
|
|
|
|
```shell
|
|
make build
|
|
```
